I've searched this multiple times first off I just want to know how good the eibach springs compared to stock is handling wise. Now for the second question I was looking at the carbon c-pillar bar. Is this bar removable with like quick releases? I'm looking for handling upgrades that are also practical to the car such as keeping the fits cargo room readily available when I need it I also saw a bar that attached at the seat belts by the ceiling let me know thank you

 

best bet is coilovers if your hardcore (I have tanabe springs and they help a lot too and a lot cheaper), rear sway bar, and wider tires.

agreed
1 wider tires or new rims and tires
2 lowering springs or coil overs
3 rear sway bar

thats a good start. and if you notice after
that you want more keep going with other stuff.

I have 2 and 3 and it made a big difference. Now
i'm waiting for the tire to wear out so i can
get 205's

 

I'm looking at the ssr type c rims size around 17X7.5 is will I have rubbing issues with lowering springs and is 7.5 a well sized width for handling, I used to have 17X10 on my truck and it didn't handle as well as I thought and after the rsb that's when I should start tensioning up the chassis?
Thank you
